Celestial Mechanics and Dynamical Astronomy Open Access paper on long-term density propagation techniques is out!

The latest paper by PhD candidate Pan Sun, in collaboration with Camilla Colombo, Mirko Trisolini, and Shuang Li compares two methodologies for long-term density propagation. Specifically, it compares the continuity equation approach against the Gaussian mixture model approach. The paper focuses on the modelling of the 2D phase space long-term density evolution for high-altitude ad high area-to-mass ratio satellites. The study considers the influence of Solar Radiation Pressure and Earth’s oblateness using semi-analytical methods for a fast yet meaningful understanding of the long-term evolution of the phase-space density. The efficiency and validity of the density propagation are demonstrated and compared between the density evolution equation and the Gaussian mixture model with respect to standard Monte Carlo techniques.
